4 Claims. (Cl. 229-55) This invention relates to containers and more islltiecically lto containers formed of paper or Due to the present shortage of sheet metal for use ascontainers, it is very desirable and necessary to manufacture containers for holding such materials as paints. dyes, stains, foodstuls, etc. from materials that are plentiful. One of those which is available is paper. While the use of paper as containers is well-known, the majority o1 these are only designed for relatively short life, such as ice cream containers that will only be in use for a few hours and then discarded or they are not adapted to retain-moisture and have little mechanical strength.

It is therefore an object of our invention to provide a container capable of retaining liquids over a substantial period of time.

It is a further object of our invention to provide a container capable of retaining a liquid and of substantial mechanical strength to withstand shipment.

It is a still further object of our invention to provide a container which may be sealed and retain substances over a period of time.

It is a still further object of our invention to provide a container formed entirely of paper that may be sealed to retain substances over a period of time. I

With these and other objects in view which will become apparent as the specification proceeds, the embodiments of our invention will be best understood 'by reference to the followilig specification and claims and the illustrations inthe accompanying drawing, in which:

Figure 1 is a vertical section through a container embodying our invention;

Figure 2 is a vertical sectiog/tliiugh the up- Der portion of a container s owing a modied form of cover and upper ring;

' Figure 3 is a vertical section through the lower portion of a container showing the bottom construction of modified form; and

Figure 4 is a bottom view of the base shown in Figure 3 with parts being broken away and shown in section.

Referring now more specically to Figure 1, there is shown therein a cylindrical casing 2 which is formed by winding a plurality of layers 4 of paper on a mandrel which are all glued together. In one end of the cylinder is supported a composite disc assembly 6 formed of two outer larger cardboard discs 8 and Ill, and one inner disc I2 having a slightly smaller external diameter. When this is in place the outer vsurface of the casing is grooved as at I4 to force J :formed of rings.

an inner rib I6 into the space thus provided by the smaller disc I2. This locks the assembly into the cylinder and forms `the base of the container. The outer end of the cylinder 2 is then crimped in as at I8 to assist in holding the base in place.

A ring assembly 20 is mounted in the opposite or upper end of the cylindrical casing and is Here again the inner ring is oi slightly smaller external diameter to provide a groove around the ring. When this ring assembly is in place, the outer surface of the cylinder is groovedl as at 22 to force a rib 24 into the external groove of the ring assembly and secure it in place.

The ring assembly then provides a central opening 26 therethrough which allows the containers to be lled with whatever is desired. A top assembly 28 formed of a plurality of discs of cardboard is located in the top to act as a closure member. The lower discs 30 are of the same diameter as the opening 26 in the ring and t tightly therein. The upper disc 32 is of the same diameter as the inside of the cylinder 2 and extends over the top of the ring assembly to the cylinder wall. In Iactual sealing glue or other suitable adhesive is applied prior to inserting the top assembly or cover and this seals the top to the container. It is to be noted in this respect that the upper ring assembly is mounted down within the upper end of the cylinder approximately the thickness off the upper disc 32 of the top assembly so that when the latter is in position it will be flush with the upper end of the cylinder.

The inner surface of the container may be sized by suitable substances if desired and the upper disc 8 of the bottom which is cardboard ma.\y\be replaced by a disc of plastic material if the substance in the containers must be stirred up prior to use.

Figure 2. shows a modified form of top ring construction in'which the upper ring assembly 2n is substantially the same as the ring 20 but the center ring 34 thereof is of smaller internal as well as external diameter and thus provides a lip 36 which extends a short distance into the central opening. The ring assembly is secured to the cylindrical casing as in the previous case. The intermediate small disc 38 of the cover member 28' is also of slightly smaller diameter than the other two and allows the lip 36 to snap into the opening thus formed when the cover is inserted to form a more secure mechanical interlock.

Figures 3 and 4 show a. modied form of bottom for the containers in which the same is. formed by integral triangular leaves 40 which are folded over as the multiple layers that form the cylinder walls are rolled. The lower edge oi the paper is out in sawtoothecl form to provide the triangles which when bent over overlie each other to form an` integral base. A -disc 42 is provided' inside the cylinder and against which the leaves may be pressed and glued. 'I'his disc I2 may be either cardboard or plastic as desired.

It is-thus evident that we have provided a simple, rugged container which may be sealed and which will retain a liquid or food satisfactorily.

We claim:

l. In a container, a cylindrical housing formed of a plurality of layers of concentrically wound layers of which has a smaller external diameter than the other layers to form a groove in the outer periphery thereof. internal ribs formed adjacent each end of the cylindrical housing to project into the grooves in the base and ring and retain them in position, and a laminated closure member fitting within the annular ring and extending over the top thereof to the cylinder wall.

3. In a container, a cylindrical casing, an annular ring having substantial thickness and a groove in its external periphery and a rib on its internal periphery, a rib on the inner surface of the casing to t-into the-external groove on the ring to support it in place and a cover having a portion whose periphery is the same as that o`f` the inner opening of the annular ring and a portion of'larger periphery, said portion of smaller paper glued together, a laminated base member 'formed of a plurality of discs, one of the interl retain them in position.

2. In a container, a cylindrical housing formed of a plurality of layers of concentrically wound paper glued together. a laminated base member formed of a plurality of discs, one of the intermediate dlscs having a smaller diameter than the outer ones to form a groove in the outer surface, a laminated annular ring one of the inner periphery having a groove therein into which the rib on thel inner surface of the ring projects to secure it in place, the larger diameter portion of the cover overlying the ring.
